Merge tag 'usb-for-v5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next
Felipe writes:
usb: changes for v5.3 merge window
The biggest part here is a set of patches removing unnecesary variables
from several drivers.
Meson-g12a's dwc3 glue implemented IRQ-based OTG/DRD role swap.
Qcom's dwc3 glue added support for ACPI, mainly for the AArch64-based
SoCs.
DWC3 also got support for Intel Elkhart Lake platforms.
